Chapter 35 of the Sai Satcharitra uses a specific animal analogy to illustrate how devotees were sustained by Sai Baba. What is this analogy and what does it convey?

In Chapter 35 of the Sai Satcharitra, the author uses a beautiful analogy to explain the profound and sustaining power of Sai Baba's presence. The text states, "We are like the young ones of a tortoise, nourished only by a glance." This imagery conveys that just as a mother tortoise is believed to nourish her offspring simply by looking at them from afar, Sai Baba's mere glance was enough to provide complete sustenance to his devotees. The chapter further elaborates on this marvel, explaining that this glance alone could take away all feelings of thirst and hunger, leaving the devotees feeling completely satisfied and content without the need for physical food or water.
